DETAILED DESCRIPTION OF THE INVENTION

It is needed to state that embodiments and all element limitations in all embodiments may be combined in the case of no conflicts. The present invention will be described in detail in the following combining figures and embodiments. To facilitate the description, the direction shown in FIG. 1 is as a standard in the embodiment.

Referring to FIG. 1 to FIG. 5, an embodiment of the present invention provides an electronic cigarette 100. The electronic cigarette 100 is an integral electronic cigarette, including a housing 1, and the housing 1 is an integrated shell. The housing 1 is hollow cylindrical. One end of the housing 1 is inserted with a mouthpiece cover 33, and the other end of the housing 1 is sealed by using a bottom cover. The bottom cover and the housing 1 are integrally formed to prevent the bottom cover falling off when using. The housing 1 defines an air inlet at the bottom thereof, and the housing 1 also disposes a working indication light (not shown) at the bottom thereof. The housing 1 is made of any one of the following materials having required hardness such as metal, plastic, wood or paper material.

The electronic cigarette 100 also includes an atomizer 21 which is disposed in the housing 1 and operable to vaporize e-liquid to aerosol, a liquid-storage member 37 for storing e-liquid, a liquid-isolating member 31 for preventing e-liquid leaking out, a battery 36 and a partition member 38 disposed between the liquid-isolating member 31 and the battery 36.

The housing of the electronic cigarette 100 disposes an atomization device (not labeled) operable to vaporize e-liquid to aerosol therein, and the atomizer 21 is one part of the atomization device. The atomization device also includes a control board 22 for controlling the atomizer 21 working and a control board bracket 23. The control board 22 is disposed in the control board bracket 23. On the control board 22 disposes a mini pneumatic switch operable to control the circuit conduction to make a heating wire 211 start working The atomizer 21 includes a heating wire 211 and a liquid-guiding member 212 operable to absorb e-liquid and support the heating wire 211. The heating wire 211 winds on the liquid-guiding member 212. The liquid-guiding member 212 can absorb and store e-liquid, and may be made of fiberglass or other materials capable of absorbing and storing liquid such as cotton material. In the embodiment, the liquid-guiding member 212 is accommodated and fixed on a catheter 35 to be described below. Two ends of the heating wire 211 pass through the liquid-isolating member 31 and electrically connect to a positive electrode and a negative electrode of the control board 22 respectively.

Referring to FIG. 2, the liquid-isolating member 31 includes a seat body 311 fitting with an inner wall of the housing 1. The seat body 311 uses an outer wall thereof to be tensioningly fixed on the inner wall of the housing 1. A central portion of the seat body 311 axially extends outwardly and forms an infixing column 312 operable to infix with the catheter 35. A central portion of the liquid-isolating member 31 defines an air vent 313 axially through the infixing column 312 and the seat body 311. On the sidewall of the seat body 311 forms a tensioning ring 314 which is integrally formed with the seat body 311. The seat body 311 is tensioningly fixed on the inner wall of the housing 1 by using the outer wall and the tensioning ring 314. The seat body 311 further defines a threading hole 315 therein, which is located at an outside of the infixing column 312 and axially passes through the seat body 311.

In the embodiment, the liquid-isolating member 31, the mouthpiece cover 33 and a portion of the housing 1 jointly forms an enclosed space which is similar to a traditional e-liquid cup for storing e-liquid and operable to store e-liquid. The liquid-isolating member 31 and the mouthpiece cover 33 are opposite to each other and spaced apart to be fixed on the inner wall of the housing 1. The liquid-isolating member 31 is operable to prevent the e-liquid in the liquid-storage member 37 leaking out from the enclosed space. The enclosed place disposes the liquid-storage member 37 therein for storing e-liquid, and operable to support the catheter 35 of the liquid-storage member. The liquid-storage member 37 is sheathed and supported around the catheter 35 and located between the liquid-isolating member 31 and the mouthpiece cover 33. Two ends of the liquid-storage member 37 abut with the liquid-isolating member 31 and the mouthpiece cover 33 respectively so as to be axially fixed.

The mouthpiece cover 33 is inserted into the housing 1 and is tensioningly fixed on the inner wall of the housing 1 by using an outer sidewall thereof. The mouthpiece cover 33 is cylindrical, and includes a main body 330 encircled by a sidewall (not labeled) and a top wall (not labeled). The central portion of the mouthpiece cover 33 disposes an infixing column 331 operable to infix with the catheter 35. The central portion of the infixing column 331 disposes an air vent 332 axially through the mouthpiece cover 33. Between the infixing column 331 and an inner sidewall of the mouthpiece cover 33 forms an annular cavity 333 for accommodating the catheter 35. The top wall of the mouthpiece cover 33 radially extends outwardly to form a limit flange 334 fitting with the housing 1. When the e-liquid in the liquid-storage member 37 is exhausted, the mouthpiece cover 33 is pulled out to continue to add e-liquid into the housing 1.

The catheter 35 is used to support the liquid-storage member 37 and is simultaneously used for supporting the liquid-guiding member 212, and further serves as a path for aerosol entering into the housing 1 which is produced from the e-liquid being vaporized by the atomizer 2. In the embodiment, the catheter 35 is a hollow pipe with through hole and may be made of plastic or fiber materials such as fiberglass, and includes a top portion and a bottom portion. The top portion infixes with the infixing column 331 of the mouthpiece cover 33, and the bottom portion abuts with the liquid-isolating member 31 and is sheathed and fixed on the infixing column 312 of the liquid-isolating member 31, that is the infixing column 312 of the liquid-isolating member 31 is inserted into and fixed in the catheter 35. The through hole of the catheter 35 communicates with the air vent 332 of the mouthpiece cover 33 and the air vent 313 of the liquid-isolating member 31 respectively. The catheter 35 defines a slot 351 through the wall and operable to support and fix the liquid-guiding member 212. The liquid-guiding member 212 across the catheter 35 and two ends of the liquid-guiding member 212 respectively pass through the slot 351 and abut with the liquid-storage member 37 to absorb e-liquid for the heating wire 211 atomizing.

The liquid-storage member 37 is operable to absorb and store e-liquid to facilitate the atomizer 2 vaporizing the e-liquid subsequently, and may be made of materials capable of absorbing and storing e-liquid such as cotton material. The liquid-storage member 37 is hollow cylindrical structure, and is sheathed around an outside of the catheter 35 and tensioningly fixed with an outer wall of the catheter 35 to be supported. An inner sidewall of the liquid-storage member 37 also abuts with the liquid-guiding member 212. E-liquid seeps from the liquid-storage member 37 into the liquid-guiding member 212 and is vaporized into aerosol by the heating wire 211 after being absorbed.

Because the housing 1 of the electronic cigarette is made of materials with required hardness, in order to make an inhalation rod 90 of the electronic cigarette having a good softness when using and having better feeling and taste when holding and smoking, the housing 1 is sheathed with at least one layer of the soft paste layer 7 at the outside thereof. In the embodiment, the number of the soft paste layer 7 is one. The soft paste layer is made of any one of the following materials such as paper, cotton or soft plastic. The soft plastic is made of any one of the following materials such as polyethylene terephthalate (PET), ethylene-vinylacetate copolymer (EVA) or polyvinyl Chloride (PVC).

When smoking, ambient air enters from the air vent at the bottom of the housing 1, and passes through the air vent 313 of the liquid-isolating member 31, the through hole of the catheter 35 and the air vent 332 of the mouthpiece cover 33, then flows out of the housing 1, forming an internal air path of the electronic cigarette. The air flows smoothly both in the internal and outside of the electronic cigarette. Certainly, ambient air may also enter into the housing 1 from the air vent on the mouthpiece cover 33 directly, and then reaches in the catheter 35.
